Troodon (/ ˈ t r oʊ. ə d ɒ n / TROH-ə-don; Troödon in older sources) is a former wastebasket taxon and a potentially dubious genus of relatively small, bird-like theropod dinosaurs definitively known from the Campanian age of the Late Cretaceous period (about 77 mya). It includes at least one species, Troodon formosus, known from Montana.
It probably had good vision in light and very good night vision. It had a long, low head, a depressed muzzle, sharp teeth and a relatively large brain. Swift and smart, like its North American cousin Troodon, Saurornithoides probably scoured the Gobi Desert, looking for small mammals or reptiles to eat. Like other troodontids, it had an ...
Ostracods, or ostracodes, are a class of the Crustacea (class Ostracoda), sometimes known as seed shrimp. Some 33,000 species (only 13,000 of which are extant ) have been identified, [ 2 ] grouped into 7 valid orders. [ 2 ]
Troodon bakkeri (Carpenter, 1982) Pectinodon is a genus of troodontid theropod dinosaurs from the end of the Maastrichtian age of the Late Cretaceous period (66 mya ). It currently contains a single valid species , Pectinodon bakkeri (sometimes classified as Troodon bakkeri ), known only from teeth.
An edible seed [n 1] is a seed that is suitable for human or animal consumption. Of the six major plant parts, [ n 2 ] seeds are the dominant source of human calories and protein . [ 1 ] A wide variety of plant species provide edible seeds; most are angiosperms , while a few are gymnosperms .
Commercial bird food is widely available for feeding wild and domesticated birds, in the forms of both seed combinations and pellets. [9] [10]When feeding wild birds, the Royal Society for the Protection of Birds (RSPB) [11] suggests that it be done year-round, with different mixes of nutrients being offered each season.

As a verb, to spawn refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and ...
More recent findings do not support this; sauropods are now thought to have been fully terrestrial animals. [61] A study of diplodocid snouts showed that the square snout , large proportion of pits, and fine, subparallel scratches of the teeth of Apatosaurus suggests it was a ground-height, nonselective browser .
